Abstract

The aim of this work is to study the plan of testing actions to compensate for disturbances in uncontrolled conditions furnaces for heating of metals before rolling. We solve the problem of the formation of the input signal of testing to determine the impact of dynamic characteristics of an object by its characteristic. In this paper, to compensate for the low-frequency and random perturbations offering etsya method of forming the signal identifying the impacts, on the basis of a system of orthogonal Walsh functions. Uncontrolled process disturbance acting on the actual thermal energy objects distort the information on their dynamic parameters, which leads to deterioration of quality control. And it is possible to note the characteristics of Ob-project have considerable inertia, and low-frequency perturbations, the characteristics are the vertical and horizontal drift. The impact of these disturbances can be considerable, but reduced by the proper formation of test input signal influences. Alarm influence in the identification of the inertial object with delay was tested in a special unit and showed high efficiency.
